About the 2010 GMC Terrain
1st generation Terrain (2010-2017), first model year.
GMC positioned the Terrain as a smaller crossover that still felt like a GMC SUV: bold styling, upright driving position, flexible cargo space, and what it called professional-grade capability. The pitch centered on giving shoppers big-SUV comfort and usefulness in a more fuel-efficient package. Compared with rivals, GMC leaned hard on the Terrain’s tough-looking design, roomy sliding rear seat, quiet cabin, and strong highway fuel economy from the four-cylinder.
The SLE serves as the practical, well-equipped Terrain, with a rearview camera, USB audio, a power driver’s seat, and a sliding and reclining rear seat. The more upscale SLT adds heated leather-appointed front seats, remote start, Bluetooth, and premium audio, while a 3.0-liter V6 is offered on upper versions.
